We've had donors ask if they will get a monthly confirmation upon automated recurring gift processing. Since we do not send acknowledgements for recurring gifts, it would be helpful to provide this documentation automatically to donors for reasons such as providing them support to then submit a matching gift. Even for bills that are on 'auto pay', one still gets an email for awareness even though there is no action needed.
I agree this would be helpful. As a recurring donor myself, the monthly reminder that my card had been processed successfully is appreciated. It makes it really easy at tax time to find receipts and not have to wait on a consolidated one.
